CROSS-BEA-RER.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed July '7, 1905. Serial No. 268,609.

To all w/wm, it may concern:

Be it known that I, ALLEN E. OSTRANDER, a citizen of the United States, residingat Paterson, Passaic county, New Jersey, have invented a certain new and useful Improvement in Cross-Bearers, of wh ch the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top plan view of a cross-bearer constructed in accordance with my invention. Fig. 2 is an elevational view of the cross-bearer. Fig. 3 is a sectional view on the line 3 3 of Fig. 2, and Fig. 4 is a sectional view on the line L 4 of Fig. 2.

This invention relates to CI'OSSr'bGiLI'GI'S for railway-cars and one of the objects of the invention is to provide a cross-bearer of the plate-girder type which will be light, durable, and strong, so as to be readily adapted to perform the service for which it is intended.

In the construction illustrated in the drawings, 1 designates the center sill, consisting of two parts. Each part is formed of a plategirder or web portion 2, having an integral outwardly disposed flange 3 at its upper edge and oppositely-disposed flanges 4 and 5 at its lower edge, said flanges 4 and 5 being parts of angles which are secured to the web 2-by rivets. Interposed between the members of the center sill is a filler 6, having flanges on all edges, the side flanges being secured to the webs of the center sill, while the top and bottom flanges are secured to a top cover-plate 7 and the flanges 5, respectively. The filler 6 is approximately the same height as the height of the center sill, as will be apparent by reference to Fig. 2.

8 and 9 designate the side sills, which are illustrated as being in the form of channels whose flanges are disposed inwardly or toward the center sill. lVebs 10 and 11 connect the center-sill members with the side-sill members, and these webs are flanged on all edges. Each web is, wider at the center sill than at the side sill. The top edge is comparatively straight, while the lower edge is upwardly inclined toward the side sill, to which it is secured by its end flange. Aflat strip comprising the top plate, and which is designated by the numeral 12, extends transversely across the center sill and is secured to the upper flanges oi the respective webs, but terminates short of the ends of the respective webs 10 and 11. This member 12 might properly be termed the tension" member of the girder, the compression member for each web being in the form oi a channel 13, secured to the lower flange of each web and to the center sill. These channel compression members are wider at the center sill than at the points distant therefrom, and in side elevation the side flanges 14 are approximately wedgcshaped. It will be observed that the compression members 13 are above the bottom edges of the center sill and the fillerplate 6 will act as a reinforcement for the compression members when load is applied to the cross-bearer.

The construction herein described is such that a strong and durable cross-bearer will be provided which will eiliciently resist the strains to which such a device will be subjected.

It will be observed that the corners of the webs l 0 and 1 1 are cut out so that the webs will be secured beneath the top flanges of the center sill members and be confined between the rnwardly-projecting flanges of the side sills, while the tops of the webs are flush with the top cover-plates. One reason for this is to add rigidity to the cross-bearer and provide neat and convenient forms of connections.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cross-bearer for cars, the combination with center-sill members spaced apart, a diaphragm-filler between the center-sill members, a continuous top cover-plate connected to the center-sill members and the diaphragm flller, webs projecting in opposite direct ons from the center-sill members, and a channelsection secured to the under side of each diaphragm 0n the outer sides of the center-sill members; substantially as described.

2. In a cross-bearer Ior cars, the combination with a center sill comprising members having outwardly-disposed upper flanges, of webs secured to and projecting from opposite sides of the center sill, said webs having flanges on their upper edges which project beneath the 0utwardly-disposed flanges of the center-sill members to which they are secured, the top edges of the Webs at all other portions being not lower than the tops of the center sill, and a pressed-steel compression member secured to the bottom of each web and connected to the webs of the center-sill members; substantially as described.

3. In a cross-bearer for cars, the combination With a center sill, of webs secured to and projecting from opposite sides of the center sill, and a pressed-steel compression member secured to the bottom of each Web, the inner ends of said pressed-steel compression members abutting the center sills, from which point they gradually diminish in width to- Ward the outer ends of said Webs; substantially as described.

4. In a cross-bearer for cars, the combination with a center sill, outwardly-projecting webs carried by said center sill, and pressedsteel channel members 13 connected to the bottoms of said Webs and having their inner ends abutting the center-sill substantially as described.

5. In a cross-bearer for cars, the combination With a center sill, webs connected to the sides of the center sill and having their bottom edges below the neutral axis of the center sill, and pressed-steel compression members secured to the bottoms of said webs and to the sides of the center sill, said compression members having downwardly-pr ojecting flanges wider near the center sill than near scrlbed.

7. The combination with a center sill hav- 'ing a boxed-in diaphragm connecting the center-sill members and of a height equal to the height of the center sill, a continuous cover-plate .for the center sill and connected to said diaphragm, the webs and 11 connected to said center-sill member, side sills connected to the ends of the Webs, and compression members connected to the center sill and Webs and terminating short of the -side sills; substantially as-described.

In testimony whereof I hereunto affix my signature, in the presence of two Witnesses, this 27th-day of June, 1905.
